# POST-LOCK HOOK
#
# The post-lock hook is run after a path is locked.  Subversion runs
# this hook by invoking a program (script, executable, binary, etc.)
# named 'post-lock' (for which this file is a template) with the 
# following ordered arguments:
#
#   [1] REPOS-PATH   (the path to this repository)
#   [2] USER         (the user who created the lock)
#
# The paths that were just locked are passed to the hook via STDIN.
#
# Because the locks have already been created and cannot be undone,
# the exit code of the hook program is ignored.  The hook program
# can use the 'svnlook' utility to examine the paths in the repository
# but since the hook is invoked asyncronously the newly-created locks
# may no longer be present.
#
# The default working directory for the invocation is undefined, so
# the program should set one explicitly if it cares.
#
# On a Unix system, the normal procedure is to have 'post-lock'
# invoke other programs to do the real work, though it may do the
# work itself too.
#
# Note that 'post-lock' must be executable by the user(s) who will
# invoke it (typically the user httpd runs as), and that user must
# have filesystem-level permission to access the repository.
#
# On a Windows system, you should name the hook program
# 'post-lock.bat' or 'post-lock.exe',
# but the basic idea is the same.
#
# The hook program runs in an empty environment, unless the server is
# explicitly configured otherwise.  For example, a common problem is for
# the PATH environment variable to not be set to its usual value, so
# that subprograms fail to launch unless invoked via absolute path.
# If you're having unexpected problems with a hook program, the
# culprit may be unusual (or missing) environment variables.
#
# CAUTION:
# For security reasons, you MUST always properly quote arguments when
# you use them, as those arguments could contain whitespace or other
# problematic characters. Additionally, you should delimit the list
# of options with "--" before passing the arguments, so malicious
# clients cannot bootleg unexpected options to the commands your
# script aims to execute.
# For similar reasons, you should also add a trailing @ to URLs which
# are passed to SVN commands accepting URLs with peg revisions.
#
# Here is an example hook script, for a Unix /bin/sh interpreter.
# For more examples and pre-written hooks, see those in
# the Subversion repository at
# http://svn.apache.org/repos/asf/subversion/trunk/tools/hook-scripts/ and
# http://svn.apache.org/repos/asf/subversion/trunk/contrib/hook-scripts/
